WATER-CLOSET..

Application filed December 5, 1927, Serial No. 237,684, and in Sweden .May 17,` .1927,

rlhis invention relates to a water closet in which a thorough flushing takes place automatically, both when the movable partv of the seat, after having been pressed down while a person sits on it, automatically resumes its initial position when the persons weight is removed, and also when the movable part of the seatis lowered. to its initial position, after having been fully lifted up.V

As an example, a water closet according to this invention is shown in the accompanying drawings. Fig. 1 shows a vertical section of the closet with all the parts in initial posit-ion. Fig. 2 shows the upper part of t-he closet in vertical section with the seat pressed down and the flushing member in raised position and with the float in lowered position, the tap being' open. Fig. 3 shows the upper part of the closet in vertical section with the seat fully lifted up. the flushing member in raised position and with the iloat also in raised position, the tap being closed.

A description of the water closet shown as an example: Y

In or at the upper part of the water closet 1 there is a chamber 2, flushing water chamber, arranged beneath the upper edge4 of the bowl 3. VThis chamber is mostly occupied by a member 5, the flushing member` which normally rests on the bottom 6 of the flushing chamber, which bottom in asuitable incline rises to the upper edge 4f of the bowl 3. The bottom surface 7 of the flushing member is made to correspond with the bottom surface of the liushing water chamber. The flushing member 5 isv made in the form of a container with greater depth than the flushing water chamber. ln the'wall of the flushing member which is turned towards the bowl 'of the closet, is arranged a swingable valve 8 with its valve seat 9. @ne end of a chain 10 is fastened in the valve, while its other end is fastened in a cover 11, which closes cap 12, which is placed. above the flushing water chamber on the closet. The length of the chain 10 is so adjusted, that when the flushing member rests on the bottom of the flushing water chamber. the valve 8 is lifted b the chain 10 from the seat 9.V j

On each side of the flushing member 5 is arranged a two armed lever 13, which is turnable round a pin 14, which is fastened to the closet. One armof the lever is'turnably connected with the flushing member 5 by a pin 15. rlllhe other arm of theilever actuated by a pin press 16, which vpasses through a hole 17 in the upper part of the closet 1. The seat is in a usual manner'made in two parts,the` stationary part 18, which is screwed to the closet 1, and the movable part 19. Both parts of the seat are connected Vivith each other by means of hinges 20. By

means of the levers 13 and the press'pins 16 the movable part of the seat 19 is helda little raised above the closet 1, when the flushing member rests on the bottom of the flushing chamber, Fig. 1. Both arms of the levers and the length of the press pins 16 are adjusted in such a way that when the movable part of the seat 19 is pressed down against the closet, as shown vin Fig. 2, the flushing member, owmg to the actuation of the press pins 16 on the levers 13, is raised to the desired height by the levers. v Y

To the arm of the lever 13, which is joined with the flushing member 5 is fastened one end of a chain 21, which by its other. end 1s connected to Vthe movable part 19 of the seat, and the length of which is adjusted so that when the movable part 19 ofthe seat is -fully lifted up, as shown in Fig. 3, the flushmg member 5, by theactuation of the chains 21 on the levers 13, is raised to the rdesired height. Each fastening point of the chain 21 to the lever 13 and the'movable part 19 of the seat respectively are so chosen, that when the seat is fullyv lifted up, these fas* tening points and the hinge 20, of the mov-V able seat, lie in a straight line, Fig. 3, in such a way that no turning momenttakes rplace on the movable part of the seat.

In the flushing chamber there is a float 22, which is fastened to a bar 23, which is con. nected with one arm of a lever 25 pivotal on a stationary pin 24;, the other armof said.

klever being connected with a bar 26, which,

when being raised, actuates a tap t not shown in the drawing) in such away that this is opened, and the flushing vwater is conveyed to the flushing member and the flushing water chamber through the pipe 27.

rlhe described closet works in thefollow-i ing manner: y When the closet is not being used, the different parts assumev the initial position, shown 'in Fig. 1; .f'lfhe flushing member 5 rests on the bottom 6 of the flushing vchamber, and the chain 10 between the valveS and the cover 11 keeps the valve S open. The

When one sits on the movable part 19 of.

the seat, the press pins 16 are pressed against the levers 13 in such a way that these are turned around the stationary pins 14. The flushing member 5 is then raised, and when the seat is entirely pressed down, the flushing member has reached the level, which is shown in Fig. 2. The chain 10 between the valve 8 and the cover 11 is then slackened, so that the valve 8 has fallen down against the seat 9 and tightened against the same. The chains 21 between the levers 18 and the movable par t 19 of the seat are also slackened and have thus not actuated the levers 13. The water in the flushing water chamber 2, owing to the raising of the flushing member 5, has sunk from the level a-a shown in Fig. 1 to the level 5 5 shown in Fig. 2. The weight of the float 22 then acts upon the lever 25, so that this isV turned around the pin 24 and raises the bar 26, which then actuates the tap, not shown, so that this isl opened and the flushingwater'streams in through the pipe 27. This flushing water streams into the flushing member 5 and ills this, whereafter it runs over the flushing members edges to the flushing chamber 2. When the water surface in the'lushing chamber 2 has risen to the level a-a (see FigB) ,the float 22 again floats and actuates the lever 25 in such a way, that the lever is turned around the pin 24, whereby the bar 26V is lowered, the tap not shown is closed and the admission of flushing water ceases. As shown in Fig. 3 both the flushing member and the flushing water chamber are filled with flushing water. y I Y When one rises from the movable part 19 of the seat, the flushingy member, owing to its own weight and the weight of the water it contains, sinksV to its initial position according to Fig. 1, whereby the movable part 19 of the seat is raised to its initial position by the levers 13 and the press pins 16. Vhen the flushing member sinks it Jforces trom the flushing water chamber a quantity of flushing water, corresponding to the volume of that part of the flushing member 5 which has been lowered into the lushing water chamber. When the flushing members sinks, the chain 10 is stretched and vopens the valve 8 from its seat 9, whereby the amount of water over the water level a-a in theushing member iows out of the same. The amount of flushing water forced out of the flushing chamber 2, as well as the amount of flushing water ilowing out of the flushing member 5 streams to the down, and as described above. As when thev seat is entirely lifted, the fastening points ot the chains 21 and the turning point i. e. the hinge 2O oit' the movable part ot the seat, come in a straight line, no turning moment on the movable part of the seat takes place, and thus this movable part remains in its lifted position in the same way as an ordinary seat. l/Vhen the seat is lowered, the llushing member sinks, whereby all-the parts act in the same way as when the flushing member sinks, when the pressure on the seat is released, and as described above.

1n a closet according to this invention an equally thorough flushing takes place automatically, both when the movable part of the seat after having been pressed down while one is sitting on it, automatically returns to its initial position, when one rises from it, and when the movable part of the seat after it has been fully lifted up is again lowered to its initial position.

Closets, arranged according to this inven tion, can be made in many other ways than that described as an example, without deviating from the idea of the invention.

Having now described our invention, what we claim as new and desire to secure by Letters Patent is:

1. A water closet of the character described, comprising a flush bowl and a reservoir chamber separated from each other by an overflow' wall, a tank suspendedwithin the reservoir and arranged to be lowered into the water chamber to ydisplace theL water therein over `the said overflow wall, and into the flush bowl,

means to elevate the tank above the normal water level in the reservoir maintained by the overtlow wall, a valve disposedin the tank and automatically opened and closed by the lowering and raising, respectively, of the tank within the reservoir to discharge the contents of the tank into the reservoir and thence to the bowl, and al float controlled means operating automatically with a drop in the water level in the reservoir to supply water to the tank and reservoir when the said tank is in raised position.

2. A water closet of the character described, comprising a flush bowl and a reservoir chamber separated from each other by an over flow wall, a seat to be raised and lowered over said flush bowl, a tank suspended within the reservoir `and arranged to be lowered therein to displace the water over the overiiow wall and into the flush bowl, means operated by the lowering of the seat to rest on the bowl to elevate the tank above the normal water level inthe reservoir maintained by the said overflow wall, a valve in the tank and in closed position when the tank is in elevated position, means for automatically opening said valve when f the tank is lowered to discharge the water in the tank simultaneously with the displacement of the water in the reservoir by the tank, and a iloat operating in the reservoir to automatically release a supply of water to till the tank and reservoir when the water level in the latter is below the normal maintained by said overflow wall.

3. A water closet of the character described, comprising a flush bowl and a reservoir chamber separated from each other by an overflow wall, the bottom wall of said reservoir chamber being disposed at an upward inclination towards the overflow wall, and a tank suspended for upright adjustment in said'reservoir and adapted to displace water in the latter into the bowl over the overflow wall when the tank is lowered, said tank having its bottom wall disposed at an inclination corresponding to that of the'bottom wall of the reservoir to facilitate the flow of water from the reservoir to the bowl when being displaced by the tank.

il. A water closet, as claimed in claim 2,` in

prises a lever arm pivoted adjacent one end to the interior wall of the bowl, a button operat ing in the wall of the bowl and in the path of the said seat in its position on the bowl and connected to the shorter end of the lever arm,

the opposite end of the arm being pivotally connected to thesidey of the tank, and a connection between the longer end of lever arm and the seat to hold the longer end `elevated when the seat is in full open position, whereby -the tank will be supported in its uppermost position independently of the said button.

In witness whereof, we have hereunto signed our names.
